Hyper-V Administrators Group is Missing

I have a problem with Hyper-V and the Windows Phone 8 SDK on a new Dell Inspiron Laptop.

The Laptop came with Windows 8 Home Premium, which I upgraded to Windows 8 Pro with Media Center through the Add Additional Features option.  

Once Windows 8 Pro with Media Center was installed and full patched through Windows Update I added Hyper-V and other features through the Add and Remove Features in the Control Panel.

I then checked the Local Users and Groups but the Hyper-V Administrators group is missing.  I have two other Windows 8 PC's which I installed from the Windows Pro Upgrade path and they both have the Hyper-V Administrators group in them - even before the Hyper-V features were added to them.

This appears to be an issue with the upgrade from Home Premium to Pro with Media Center not creating the Hyper-V Administrators Group.  

I have tried reformatting and reinstalling numerous times and added things in different orders but the outcome is still the same.  Unfortunately the Hyper-V Administrators Group is required in order to install and run the Windows Phone 8 SDK.

I have tried to create the Hyper-V Administrators Group with a Powershell Script which I downloaded but it does not fool the Windows Phone 8 SDK installer which still fails as the correct Hyper-V Administrators Group is a BUILTIN Account but the one which the script creates is not.

Can anyone assist with this.  Is there a way of being able to create the Hyper-V Administrators Group with the correct permissions so that I can get the Windows Phone 8 SDK installed and working with Visual Studio?

This is clearly a bug with Windows 8 (Not the Windows Phone 8 SDK)
I had the same problem with the Phone SDK saying it couldn't add the user to the group. However, I tried an app and it told me to check my BIOS. When I did that I discovered the installer hadn't completed and wanted a reboot. After the reboot still no group but the eumulator seems to be working fine...so far...

Have you resolved this? I have exactly the same issue, on an HP laptop. I am trying to uninstall Win8Pro to reinstall it, but that doesn't seem to be possible. Also, I did it in this order:
Win 8 upgrade to Pro
Install Visual Studio 2012 for Windows Phone 8
--> problem with hyper-v install ,
--> enabled in BIOS (AMD processor, so mem and vm)
--> could not enable in Windows Features
--> upgraded bios, restart
Enabled Hyper-V in windows features
On VS deploy on emulator, emulator warning shows up with 'You don't have permission',
Join hyper-v is checked, click 'retry' to run in elevated mode.
Emulator starts, says 'windows os is starting...' but eventually fails.

I have a temporary work around which allows the Windows 8 Phone Emulator to work.

 

I created the Hyper-V Administrators group using a script from here

and added myself to the group

The combination of what was in these articles got it running but there is still a bug here which needs to be fixed properly as far as I am concerned.

Thanks so much. That got me part of the way there. (I now simply get a failure to deploy rather than the Hyper-V admin error). I presume this is one of those things to fix by formatting the hard drive and starting over.  Good luck to you, and many thanks for the great reply.

I think I had the failure to deploy error the first time, as it seemed to take forever to start the emulator.

 

I think that after I followed the instructions in the above links, I started Visual Studio with elevated permissions, opened and ran a simple project for Windows Phone, it then asked me prompted me that I did not have permissions to run the emulator and did I want to add permissions, I then clicked yes.  Then closed VS and rebooted and it all worked ok from then on.

 

I also reinstalled/repaired the installation of the Windows Phone SDK at some point.

 

So you might want to try these things before the big reformat.

 

Hope you get it working ok and glad I could be of assistance.
